Technical field

The invention belongs to metal working technical areas, and in particular to one kind is processed for Z-shaped structural metal sheet metal bending Equipment.

Background technique

Traditional Z-shaped structural metal plate usually carries out bending to metal plate in a manual manner in bending process, The effect of artificial bending is poor, and bending precision is low, can not accurately be by sheet metal bent at required angle, and manual operation intensity Greatly, production efficiency is low.A kind of zigzag bronze medal bending is disclosed application No. is the Chinese invention patent of CN201711226081.7 to set It is standby, including upper die and lower die, for upper mold equipped with cope plate, lower die is equipped with lower template, and cope plate is equipped with upper mold zigzag cavity structure, Lower template is equipped with lower die zigzag cavity structure；The left side wall of zigzag cavity structure is straight wall, and the left side wall of lower template is straight wall, The left side wall of upper mold zigzag cavity structure and the left side wall of lower template are dislocated setting.Molding up and down, cuts plate It cuts, upper mold zigzag cavity structure and lower die zigzag cavity structure cooperate, and will be sheared the sheet fabrication to get off into zigzag.It should Invention completes the shearing of plate and the zigzag processing of bronze medal in the case where primary molding up and down.Utilize the equipment pair of the invention Sheet metal, which carries out Bending Processing, can promote working efficiency, improve production efficiency, but there is also following problems for the invention: (1) Bending Processing can not be carried out to the sheet metal of different bending angles；(2) Z-shaped structural metal after molding plate is in bending place shape At folding line, the fitness in the subsequent use of Z-shaped structural metal plate with other components is reduced.

Summary of the invention

(1) technical problems to be solved

The present invention provides one kind to be used for Z-shaped structural metal sheet metal bending process equipment, it is therefore intended that solves existing folding Following problem present in curved process equipment: (1) Bending Processing can not be carried out to the sheet metal of different bending angles；(2) at Z-shaped structural metal plate after type forms folding line in bending place, reduce in the subsequent use of Z-shaped structural metal plate with other zero The fitness of component.

(2) technical solution

In order to solve the above technical problems, the present invention adopts the following technical scheme:

One kind being used for Z-shaped structural metal sheet metal bending process equipment, including pedestal, side wall, conveying mechanism, the first roller Frame, the second roller frame and third roller frame roll in the first roller frame, the second roller frame and third roller frame and are equipped with roller arranged in parallel Cylinder.Conveying mechanism is fixedly connected on pedestal.

First roller frame is slidably fitted on pedestal, and first motor is fixedly mounted on side-wall outer side, inside sidewalls rotation connection There is first rotating shaft, first rotating shaft fixed sleeves are equipped with the first reversing roller for being parallel to roller, and the output shaft of first motor runs through side Wall and the one end for being fixedly connected with the second roller frame side wall, the second roller frame the other end face are fixedly connected with the second commutation for being parallel to roller Roller.Flatten unit is sliding combined on first reversing roller and the second reversing roller.Sheet metal is delivered to the first roller by conveying mechanism After on frame and the second roller frame, the rotation of the second roller frame is driven by first motor, the sheet metal in the second roller frame occurs curved therewith Song, after sheet metal is contradicted to the first reversing roller, sheet metal generates to be bent for the first time.
